chicken cam

I have been trying to figure out a reasonably priced way to set up a wireles chicken cam system that will send to my computer or possible over the web. I tried a wireless X-10 night vision cam that was supposed to have a 100 foot range, but it didn't work so sent I it back.

I've seen a couple of wired systems but I need to go wireless. Does anyone have any suggestions for equitment to do this? Michael
